Abstract: PROBLEM TO BE SOLVED: To produce trioxane by reacting formaldehyde in vapor phase in the presence of a tungstomolybdophosphoric acid catalyst.  
     SOLUTION: A formaldehyde having a water content of as low as <1 wt.%, especially <50 ppm is brought into contact with a catalyst consisting of a tungstomolybdophosphoric acid having a compositional formula H 3  PW n Mo m O 40 .xH 2 O ((n) is 4-8; (m) is 12-n; (x) is 0-32) at a temp. of 80-150°C for 1-30 sec in the presence or absence of a carrier gas (e.g. N). This catalyst is preferably supported on a carrier substance such as silicon carbide and the reaction is carried out under a formaldehyde partial pressure of 0.5-5 bar at the inlet port. High selectivity for the formation of trioxane and a high conversion close to the equilibrium conversion can be attained together with a high space-time yield by the use of the tungstomolybdophosphoric acid as a catalyst.

Filed: 1996-06-11
Abstract: PROBLEM TO BE SOLVED: To increase the capacitance of a dynamic RAM by removing a part of silicon nitride and a part of first polysilicon by etching and then removing the silicon nitride entirely. SOLUTION: A silicon nitride 17 is deposited on a polysilicon 16 forming the lower electrode of a capacitor and then the silicon nitride 17 is etched using phosphoric acid.

Title: Ink jet printer and method for regulating ink discharging speed of the printer
Inventor: SUZUKI SHOGO
IPC: B41J2/055
Filed: 1997-06-27
Abstract: PROBLEM TO BE SOLVED: To regulate an ink discharging speed of an ink jet printer by changing one of inclination and amplitude of a waveform of a driving voltage to be applied to a piezoelectric element, and altering a voltage value of a power source of an analog switch means for opening or closing a driving voltage passing route to the element. SOLUTION: In the case of regulating a discharging speed, an ON resistance of an FET for constituting an analog switch 78 is raised due to a drop of a power source voltage Vdd2 so that change of a driving waveform becomes slow to show a curved change, thereby decelerating the speed. Meanwhile, when the ON resistance is lowered, the change of the driving waveform becomes sharp to show a linear change, thereby accelerating the speed. In addition, the power source voltage is regulated by a variable resistor 95 connected to a power source circuit 94 so that a maximum value of a driving voltage Vsource has a predetermined voltage difference to the power source voltage by a Zener circuit 93. And, the power source voltage is regulated to change the voltage Vsource.  Further, a gradient of the voltage Vsource is changed by regulating current values of constant-current circuits provided in switch circuits 54, 56 of a pulse amplifier 52.
